摘要： A control server initiates a call to a first device. After creating a connection to the device, the control server reverses the direction of the message flow between the device and the control server such that the device becomes the initiator of the call (the caller) and the control server becomes the device that is called (the callee). A connection is also established between the first device, the control server and a second device that is an endpoint for the call. Early media and forking is available to the first device after reversing the direction of the message flow between the first device and the control server and the callee has been contacted. Additionally, information flows between the first device and the second device through the control server as if the first device and the second device were directly connected.
